Geometric Series HELP!!!

a/(1-r)=a+ar+ar^2.......ar^6 0<r<1

Write a MATLAB program which calculates the exact value for the geometric series for each of the following values:

i) a=1 r=1/7 ii) a=3 r=1/3 iii) a=2 r=1/9

Calculate the exact values for each and show each result in (format short e, long e, long, short, long g, and short g). Then set the display format to long, and recalculate the exact values of the function and their geometric series approximation.

Is there anyone who can help me create a script the solves the above please?! Thanks always
